The feldspar group minerals are the most abundant minerals in the earth’s crust. High concentrations of alumina (Al 2 O 3 ) and alkalis (K 2 O and Na 2 O) together with low levels of trace elements such as iron oxide (Fe 2 O 3 ) define a high quality feldspar product.

Feldspar - Uses | Britannica

Feldspar - Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Feldspar

Why is feldspar important? The feldspars are a family of silicate minerals which occur in igneous rocks. There are many different members to the feldspar group. Obviously, silicon and oxygen form the foundation for the group, but calcium, sodium, and potassium are also present. One of these elements is usually dominant, but most of the feldspars contain all 3 in varying amounts.
